"in spite of", "despite" are prepositions and "although", "though", "even though" are conjunction. So correct would be
"in spite of", "despite" + noun
"although", "though", "even though" + clause
a. Although it is cold outside, she insists on keeping her coat on.
b. Despite warm weather, she kept her coat on.
"is spite of" and "despite" can also be used as adverbial constructions with -ing.
Ex - I managed to pass my exam, despite
going out four times a week during the revision period.

b. Even if Mark told the truth, I wouldn't believe him.

b. Even though Mark told the truth, I didn't believe him.
The differences can be appreciated in this sentence
1. I'm going out, even if it rains
2. I'm going out, even though it's going to rain
In (1), we do not know whether it will rain or not in (1) so we use even if and in (2) we know that it is going to rain but we are going out anyway.even-if-although-despite-when-to-use-each-83155.html
21. "however" used at the beginning of a sentence, without a comma, means “in whatever manner” or “to whatever extent.”
