1.Alkali metal without influence of old tele network (6)
2.A metal jointing process in disarray (5)
3.Terrace - alpha 7 included (5) (the first letter in the clue to answer 7 is i which may be relevant) Wondered about Okapi but other than possibly kop meaning terrace I can't parse it properly.
4.A sound way to achieve a smooth reverse in one of these (6)
5.Up against it? Only in France (5)
6.Sounds like a good hair day for a moggy (8)
7.Sounds like infuriation when confused bird is outside ( 8)
8.Question? A gas operated weapon without numbers(3). Think it could be gnu but other than it being an anagram of gun I can't really parse the question part of it.
Any help would be welcome
For 1, the Alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Still can't improve on POSSUm but maybe others can see something
