Can a person still be a Christian and yet deny certain biblical truths?

I know Christians who accept Christ as saviour yet: 
1. Don’t believe in the incarnation 
2. Believe in evolution as God-directed
3. Don’t believe the Bible is absolute truth but is allegorical 
4. Believe there are many routes to God and salvation 
5. Don’t have a biblical worldview 

I try not to judge those who have these beliefs, but wonder if can they be termed "Christians."
