We all the Norse landed and tried to settle Newfoundland(?) but the natives fought them off. Could they keep the peace and successfully colonize North America?
Well the Norse did sail quite a bit further south than Vinland, e.g. Markland, Hvutramannaland, but they didn't have any reason to settle those areas.
Further it's not as if there was a large Norse settlement in Vinland or even Greenland to begin with. Remember these were Norse from Iceland, and the settlements were essentially resource extraction colonies; lumber mostly, which the Icelanders were desperately short of. So they had no reason to go south.
Beyond that though they'd have to go really, really, really far south to completely escape the Little Ice Age - we know settlements as far south as Jamestown Virginia were within its reach in 1608 at the height of the freeze.
Here's an odd observation: The Pope was convinced that the Greenlanders had, by the 14th and 15th century, reverted to Norse paganism. Does that sound plausible? Or is this a reflection of rumors and conjecture?

If the Greenlanders would have eaten fish (there are remarkably few fish bones found in their dumps) then they could have fled Greenland for that island south of Newfoundland.
Is there any way they could put a priority on colonization?
I didn't say abandon

(since it never occurs to vikings to try an establish peaceful contact with their neighbors).
