You can see them here, scroll down.
They're from events. All of them have charge except for TypeDS/Rod which has Devil's. All of them comes with some hit which just makes them shy of 50h yellow weapons. The list:
I forgot to mention, non-event Type weapons can be obtained by doing certain quests, for example getting enough killcount (2k per episode or something) in Maximum Attack 4 on all episodes, then getting the reward from Deepest Blue Revenue quest (forgot name). Apart from this, IIRC Beach Laughter and Beak's Cafe also can reward Type Ms, although I don't know the criteria to get them. These are the vanilla way to obtain Type M weapons. These do not come with any special and their stats are 0/0/0/0.
Imo, the best way to get started again is to level a mag to 200 asap. Either use the character reader addon to see when you can feed the mag, or use a stopwatch and feed every 3 and a half minutes.
You could raise a different mag until you are able to make panzer tail, then sell the spare mag.
Doing Challenge Mode and selling S-Rank is the best, but requires knowledge and execution. Mag shop is good but requires some meseta to start. Maximum Attack 3 is a good material/PD/PC farm when you're powerful enough to do 500 enemies clear. Box runs (Phantasmal World 3) may be profitable as well. Sell meseta/materials/grinders if you can find buyers.

DFP and EVP too, although that stacks with RR's DFP/EVP, and is often added to RR's base stat directly. I don't remember if technically the 20 DFP/EVP from RR is considered separate. At least I think it works like this.
It's actually not too bad for just about all rares but dorphon
Technically it is separate, but in practice it makes no difference. Red Ring is attached to a +20 all stat boost, and DFP/EVP are included in that, so it gives 20 extra DFP/EVP compared to how much DFP/EVP it gives from its standard shield bonuses.
