Fun Bunch of Letter Sequences

Question

Here's a batch of letter sequence puzzles for you. The goal is simple: Figure out which letters go in the blanks. Try it out for yourself and see what you can get.

Puzzle #1 K, H, D, M, D, _, _ (Solved By Bailey M)

Puzzle #2: A, B, E, F, G, H, I, J, N, P, _

Puzzle #3: I, E, H, O, I, I, E, I, I, E, _, _ (Solved By Joe Z.)

Puzzle #4: O, U, E, H, R, _, _ (Solved By Joe Z.)

The puzzles are in order from easiest to hardest.

This seems like it can be easily compared to a number-sequence puzzle, in which answers could be much too broad to be given only 3-5 letters initially. — Mark N, May 28 '15 at 20:39
I have to admit, number 2 has been harder than all the rest so far. — , May 29 '15 at 02:08
C, D, K, L, M, O - just figured it might help people to see, maybe? Still trying to see what might be common in either the present or absent letters... — Glen O, May 29 '15 at 14:46
Actually, I forgot what Sequence 2 was too! If nobody gets this soon then I'll accept the answer from Joe Z. for solving 2 sequences. — Xandawesome, Jun 13 '15 at 17:57

The letters afterward are L and W.

The letters afterward are A and U.

More to come later.
