My baby is 14 months old and only has 6 1/2 teeth.4 on top and 2 and partial on bottom. Usually by what age jaw teeth come in?

Don't worry. They are on track. All the age ranges are averages and the patterns can vary a little. Two more should come in (1 1/2) soon and then some molars in the back will likely be next (about 18 months). Then canines, then second molars. They will likely be teething off and on for the next year and a half.
Around age 2. Teeth come in when they come in. 1st molars usually arrive around the 2nd birthday. Your baby dentition seems to be completely normal.
2 Years. By the age of 24 months to 3 year, she should have a complete set of deciduous teeth. :).
