There is no fixed order, but if you really want one:
EPLL - Ua, Ub, Z, H (you already should know these from two look)
Adjacent - T, Ja, Jb, Ra, Rb, Aa, Ab, F, Ga, Gb, Gc, Gd
Diag - Y, E, V, Na, Nb
And take as long as you need. In reality, you will probably learn multiple algs for almost all the PLLs. I know 5 for multiple cases, even though I only use 1 or 2 depending on the AUF. Learn the next one when you feel like you're up for it.
Also, from the start I'd recommend learning 2 sided recog soon after you have learnt algs, or even whilst you learn them. There are trainers such as
this one that are quite good, and resources such as
this one which explain the patterns.
