1.When the edge piece is at the proper place and the corner isn't
2.When the corner is in the proper place and the edge isn't
3.When the corner is in the proper place but isn't flicked properly
Here are some ideas:
1.
RUR'U' RUR'U' RUR'U'
R' D' R U' R' D R
R' D' R U R' D R
R U' R' U2 R U' R'
LFL' RU'R'U LF'L'
Btw, if some slots are free, you can use shortcuts here, such as:
D' L'UL D
Try to look for shortcuts yourself. You will appreciate and remember them better if you find them yourself. Play around with the cube a lot, and try to find alternative solutions.
2. Yeah, standard beginners method alg for this are not too great.
F' RUR'U' R' F R
RU'R' F R' F' R
R'UR'D' RU'R' D RU'R
Btw, if some slots are still free, you can use working corner algs here, such as:
(If the FL slot is not solved yet)
D RUR' D'
D RU'R' D'
(If the RB slot is not solved yet)
D' RUR' D
D' RU'R' D
3. If the edge is also in place, I don't actually use an alg for this. I know you can do it with a 7 move sune variation, but I prefer to just dig out the pair with RU'R' or RUR', and then solve it from there.
And like others have said, click around, because there are many site that list all of these. The polish algorithm database has many different algs:
