1. บ่วงวิมาลา in this novel, the main character's name is วิมาลา. it's female's name. So I think this refers to her. And บ่วง means lariat and I think you got it right that it implies to trick. So it's "the trick of a woman called Vimala" 2. เล่ห์รักบุษบา means "The trick making someone fall for a woman named บุษบา" again บุษบา is a name. After I read the detail of the novel. บุษบา plans to make a rich man fall for her so that she will get money to pay her debt but it turns out she falls for him instead. 3. หลงกลิ่นจันทร์ means crazy about or into the smell of the moon. หลง can refer to crazy or into something as well. 4. ยึดฟ้าหาพิกัดรัก means to seize the sky to find the location of love. I have not enough time to help you translate all of these but I hope this can help you. if I have free time, I will translate all of these for you.
