Answer 2

• For first image - It looks like commit messages to me

If you do not want to see them just squash these commits.

• For 2nd Image - You can't delete the pull request but you can close pull request by doing this and if you do not to delete pull request the squash commit would be better idea.

Note that squashing a commit won't delete your commits but make multiple commits to one.

Edit
Try this command for squashing:

git rebase -i HEAD~4

Result:

pick 01d1124 Adding license
pick 6340aaa Moving license into its own file
pick ebfd367 Jekyll has become self-aware.
pick 30e0ccb Changed the tagline in the binary, too.

# Rebase 60709da..30e0ccb onto 60709da
#
# Commands:
#  p, pick = use commit
#  e, edit = use commit, but stop for amending
#  s, squash = use commit, but meld into previous commit
#
# If you remove a line here THAT COMMIT WILL BE LOST.
# However, if you remove everything, the rebase will be aborted.
