Is there a difference between välkommen and välkomna?
There is. Välkommen is for greeting one person and välkomna is for greeting multiple people.
then what is valkommet ? ^^
For something of neuter grammatical gender being welcome, e.g. "stödet är välkommet" ("the support is welcome").
Is this a Swedish custom to greet multiple people differently than greeting one person? I'm a native English speaker and in England we greet one person and multiple persons exactly the same.
Yes it is, at least when you speak directly in front of a group of people. When you are writing, you can use "välkommen" though you're directed to an audience made up of multiple (perhaps unknown) people.
I feel this was the välkommen lesson. hardly any other new words :S
How am I suppose to know how many people I'm addressing when all it says is welcome?
You can't, so both ways are accepted.
Is it wrong to say välkommen = welcome?
No, that's correct.

why did not you acepted väsägod? You said the correct answer is valkomen .
Both värsägod and välkomen are welcome. If they are not so what's värsägod?
Varsågod (note the spelling) is as in "You're welcome", not just "Welcome".
