Were there still kings in England the 1700s?

Yes, there were still kings in England in the 1700s. The Stuart monarchy was overthrown in the Glorious Revolution of 1688, and replaced with the Protestant monarchs William III and Mary II, who ruled jointly until William's death in 1702. Mary's sister Anne then succeeded to the throne, reigning until 1714. With Anne's death, the House of Stuart was restored to the throne in the person of James Francis Edward Stuart, known as the "Old Pretender." However, James was never crowned king, and was replaced by the Hanoverian dynasty with George I in 1714. The Hanoverians continued to rule England throughout the 1700s, with George II succeeding George I in 1727, George III succeeding George II in 1760, and George IV succeeding George III in 1820. The Hanoverian dynasty ended with the death of Queen Victoria in 1901.
