What females are still left of either line?

Well, you can find Targ blood in the Arryns via the marriage of Daella Targaryen and the unnamed Lord Arryn to produce children. House Plumm & House Longwater also have Targaryen blood through Elaena Targaryen and her multiple husbands including Ossifer Plumm and Alyn Velaryon. Around 197 AC (~100 years before season1/book1) a different Daenerys Targaryen was wed to Maron Martell putting Targaryen blood within the Martell lines as well.

as for the Baratheons, their blood still exists in House Swann (Kelyce Baratheon & Allos Swann), House Brownhill (Cassandra Baratheon & Walter Brownhill), House Rowan (Floris Baratheon & Thaddeus Rowan), House Blackwood (Ellyn Baratheon & Benjicot Blackwood), House Lannister (Elyanna Baratheon & Mathin Lannister), and House Crakehall (Lyria Baratheon & Garen Crakehall).

so while the names might be dead and gone, the 'lines' most certainly are not extinguished.
