PQWL:
A group of intermediate stations form a cluster/pool to form a quota.
1) Start-End Quota.
2) A single Wait list maintained across the route of the train
3) Since it is a start-end quota,...
more...

it can be applicable across any journey combination of the train, meaning for a journey leg applicable for GN/RS/RL, berths for the same can also be given from PQ.
In this case, the PNR usually needs to have more than one passenger.
If the original quota runs in WL, or doesnt has sufficient number of confirmed berths available, then PQ is used in this case.
For ex:
Pass 1 (Confirmed, PQ)
Pass 2 (Confirmed, PQ)
Pass 3 (Confirmed, GN)
Pass 4 (Confirmed, GNWL)
Note: The journey leg here comes under GNWL. Due to the unavailability of sufficient number of confirmed berths, the first two passengers are confirmed against PQ, third against GN and then the concerned Waitlist applicable across the journey leg commences.
##
However in rare occasions, PNR having single passenger are also placed against PQ in the same way.
4) Some of the stations forming PQ, are often given a share of their own. Thus either the common quota across all the PQ is first utilised and then the individual quota of the stations and/or vice versa.
Due to the above reason, most of the time you would find cases like:
Pass 1 (Confirmed, PQ)
Pass 2 (WL 56, PQ)
Here, the first pass was confirmed against the individual quota of the originating station and/or confirmed berths available for that specific journey leg and the second passenger was placed in the common Waitlist applicable from start-end.
Another reason for the above to happen may be attributed to #berthmultiplexing
5) Charting of the same happens at the originating station (Reason : Point 1)

RL Quota:
Assume when a quota is defined from Mumbai to Solapur, its NOT "Mumbai RS quota", it is "SOLAPUR RS quota".
Note :
RS quotas are identified as to where they end
RL quotas are identified as to from where they start

RSWL:
RSWL= Same as RQWL.
1) Start-Intermediate Quota.
2) A constituent of the Remote Quota group. In this case, takes place when the intermediate station does not have a share of the quota from the originating station; i.e. GNWL. Thus making the relative quota small.
3) Confirmed tickets are issued from GNWL. For combined tickets (Having more than one people in a PNR), confirmed berths can also be given from Pooled Quota. (Depends on availability).
After the confirmed berths are exhausted, most of the times it directly moves to WL.
4) Moves slowly, supports RAC. Becomes handy when the train do not support PQWL.
5) To avoid landing up in RSWL, always check for stations beyond your preferred destination station supporting GNWL.
6) RSWL is usually followed by RLWL. Most of the times RLWL is not visible due to distance restriction and/or restricted booking/s.
7) Because of the above reason, confirmation chances of RSWL in Rajdhanis is pretty low or rather uncertain. Since the system would not allow booking for the latter part of the journey, it prefers to clear the GNWL booked from start-end.
8) A train can support more than one RSWL.

RLGN/RLWL== it is the same as RLGN.
When you purchase a ticket from PRS, it would be depicted as RLWL, and upon checking the PNR online it would be shown as RLGN.
Some months back I had seen specific quota depicted as RLWL but guess the said process has been discontinued now.
1) RLGN is intermediate-end quota.
2) Has a share of the general quota/originating station= Has more number of berths= Supports RAC.
For some trains, the quota of the intermediate stations is quite low and hence it does not support RAC. In these cases, it is usually depicted as RLWL = Does not support RAC and hence has least chances of confirmation. (However as said earlier, to a lot of people RLGN and RLWL is one and the same. Hence you would need to search whether the station holding this quota has a larger share of it or just a nominal one)

As said by MST Sir here:
/blog/post/30023/6
Assume in Coimbatore Kurla Exp, some berths can be reserved only between Coimbatore and Bangalore. This is called Road side quota (RS quota : start to intermediate).
Some berths (infact the same berths) can be reserved only between Bangalore and Kurla. This is called Remote Location quota (RL quota : intermediate to end).
.
The berths on charts pasted on trains are denoted as "SBC/" and "/SBC" respectively. One cannot book a single berth in these quotas from anywhere in CBE-SBC section to SBC-LTT section. The system does not allow this, neither at booking time, nor at charting time. If some one has to overcome this issue, he needs to book 2 tickets, one upto SBC and other from SBC, to be eligible for these quotas.

For RLGN, since it shares a part of the originating station, confirmed berths are given from the General Quota and sometimes from the Pooled Quota(Kindly go through the explanation of Pooled Quota)
Pass 1 (Confirmed, GN)
Pass 2 (Confirrmed, GN)
Pass 3 (Confirmed, PQ)
Pass 4 (WL 1, RLGN)
To end the discussion, kindly note Remote Quotas are not actually quotas but are Waitlist.
Confirmed berths for all of the Remote Quotas are given from the General Quota and sometime from Pooled Quota as explained in the earlier posts. Cancellation of the Remote Quota Waitlist's happens very slow. Hence it is always advisable to be placed against GNWL.
